Everything you need to know
Percentage Error is a measure of how accurate a measurement is compared to the true or accepted value. It is a vital tool for students and scientists to evaluate experimental precision.
The Formula:
(|Exp. Value - Theo. Value| / |Theo. Value|) × 100
A low percentage error (close to 0%) indicates high accuracy, while a high percentage error suggests significant experimental variation or measurement issues.
